From 4700ebd1c355102f711dbf49ce7b22e943b1132b Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 21 Jan 2013 14:02:52 +0100 Subject: [PATCH] arch/powerpc/platforms/85xx/p1022_ds.c: adjust duplicate test Delete successive tests to the same location. The code tested the result of a previous call, that itself was already tested. It is changed to test the result of the most recent call. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @s exists@ local idexpression y; expression x,e; @@ *if ( \(x == NULL\|IS_ERR(x)\|y != 0\) ) { ... when forall return ...; } ... when != \(y = e\|y += e\|y -= e\|y |= e\|y &= e\|y++\|y--\|&y\) when != \(XT_GETPAGE(...,y)\|WMI_CMD_BUF(...)\) *if ( \(x == NULL\|IS_ERR(x)\|y != 0\) ) { ... when forall return ...; } // Signed-off-by: Julia Lawall Signed-off-by: Kumar Gala --- arch/powerpc/platforms/85xx/p1022_ds.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/powerpc/platforms/85xx/p1022_ds.c b/arch/powerpc/platforms/85xx/p1022_ds.c index 7328b8d74129..29b6a2cde56c 100644 --- a/arch/powerpc/platforms/85xx/p1022_ds.c +++ b/arch/powerpc/platforms/85xx/p1022_ds.c @@ -302,7 +302,7 @@ static void p1022ds_set_monitor_port(enum fsl_diu_monitor_port port) goto exit; } cs1_addr = lbc_br_to_phys(ecm, num_laws, br1); - if (!cs0_addr) { + if (!cs1_addr) { pr_err("p1022ds: could not determine physical address for CS1" " (BR1=%08x)\n", br1); goto exit;
